    specified element.
    locator, text
    """

    '''翻译：判断元素中是否存在指定的文本，参数：locator, text'''
    def __init__(self, locator, text_):
        self.locator = locator
        self.text = text_

    def __call__(self, driver):
        try:
            element_text = _find_element(driver, self.locator).text
            return self.text in element_text
        except StaleElementReferenceException:
            return False

1.翻译：判断元素中是否存在指定的文本，两个参数：locator, text

2.__call__里返回的是布尔值：Ture和False
